Should Google give up control of Android in watches, TVs, and cars?

One of the biggest problems with Android has been fragmentation. It has caused many headaches for developers who need to support different device configurations, and for users who may get updates late or never at all. And some have blamed this on Google not retaining more control over Android after its initial launch. Google has taken a different approach with watches, TVs and cars by keeping a tight grip on Android. But re/code reports that that might not last forever.
